metastatic survey
Systematic imaging evaluation to detect distant metastases, particularly important in choroidal melanoma staging and follow-up.
Full Definition
A metastatic survey in ocular oncology refers to comprehensive imaging studies performed to identify distant metastases, most commonly in patients with choroidal melanoma. The standard survey typically includes liver imaging (MRI or CT) since the liver is the most frequent site of uveal melanoma metastasis, along with chest imaging to evaluate for pulmonary involvement. Some protocols also include positron emission tomography (PET) scans or whole-body imaging. The timing and frequency of metastatic surveys remain areas of ongoing research, with most guidelines recommending regular surveillance for high-risk patients based on tumor characteristics and genetic profiling.
Usage
Usage note: Preferred over 'metastatic workup' in formal documentation. Can be modified as 'baseline metastatic survey' or 'surveillance metastatic survey.'
